I have a large timeline animation and I need to be able to scroll to positions within it. I'm using ScrollTrigger, and I see that it has this: https://greensock.com/docs/v3/Plugins/ScrollTrigger/scroll()   But I don't see how I'm supposed to add this to a timeline?   I've used timeline.seek(), but this doesn't update the actual scroll position.    Any help is greatly appreciated!
